Product details
Overview
SMCJ15AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode with 15V reverse standoff voltage (VRWM), 24.4V max clamping voltage (VC) at 61.5A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD environments.
For engineers reviewing the SMCJ15AQ-13-F datasheet, SMCJ15AQ-13-F pinout, SMCJ15AQ-13-F application, or SMCJ15AQ-13-F equivalent, this device is selected for high-energy surge suppression in 12V automotive subsystems where fast response (<1 ns), low clamping ratio (1.63× VRWM), and IATF 16949-manufactured reliability are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device in series with DC power rails, triggered by voltage transients exceeding 15V VRWM to divert up to 200A (8.3ms half-sine) or 61.5A (10/1000μs waveform) while limiting downstream voltage to ≤24.4V. Its glass-passivated junction ensures stable breakdown and low leakage (≤5μA @ 15V).
Designed for automotive-grade robustness, it supports operating junction temperatures from –55°C to +150°C, complies with ISO7637-2 Pulse 1 (–100V), Pulse 2a (+50V), Pulse 3a (–150V), Pulse 3b (+100V), and ISO10605 ESD (±30kV contact/air discharge), with moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000μs surges without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage | 15.0V - defines maximum continuous DC operating voltage before clamping activation |
| Max Clamping Voltage | 24.4V @ 61.5A - limits protected circuit voltage during worst-case ISO7637-2 Pulse 1 (–100V) |
| Breakdown Voltage | 16.7–18.5V @ 1.0mA - tight VBR tolerance ensures predictable turn-on across temperature |
| Leakage Current | ≤5.0μA @ 15V - minimizes standby power loss in always-on vehicle modules |
| Package | SMC (DO-214AB) - surface-mount footprint compatible with automated assembly and thermal relief pads |
| Operating Temp | –55°C to +150°C - validated for engine bay and transmission control unit mounting locations |
Pinout & Package
SMCJ15AQ-13-F uses the SMC (DO-214AB) package: molded plastic body (UL 94V-0), cathode band polarity indicator, 0.21g mass, and matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Banded End) | Anode-to-cathode forward path | Connected to system ground; reverse-biased during normal operation; conducts when transient exceeds VRWM |
| Anode (Non-Banded End) | Input/line side connection | Placed in series with protected power rail (e.g., battery feed to MCU); shunts surge energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W Peak Pulse Power | Enables compliance with ISO7637-2 Pulse 1 (–100V, 50Ω source) without derating at +85°C ambient |
| AEC-Q101 Qualified | Validated for automotive use via stress testing including HTOL, TCT, ESD-HBM/MM, and mechanical shock |
| Glass Passivated Die | Provides stable VBR over lifetime and immunity to humidity-induced parameter drift in under-hood environments |
| Lead-Free & Halogen-Free | Meets RoHS 3 (2015/863/EU) and automotive "Green" standards (<900ppm Br/Cl, <1000ppm Sb) |
| Fast Response Time | Sub-nanosecond clamping onset protects CAN/LIN transceivers and microcontroller I/O against ESD-induced latch-up |
Applications
| Body Control Module (BCM) | Infotainment Power Supply |
|---|---|
Use Scenario: 12V battery input protection for BCM microcontrollers and sensor interfaces exposed to alternator load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fuse output and DC-DC converter input to clamp transients before regulation. Use Value: Limits voltage to ≤24.4V during ISO7637-2 Pulse 1 (–100V), preventing damage to 3.3V/5V logic supplies and CAN transceivers. | Use Scenario: Surge suppression on USB-C PD and display power rails in head unit systems subject to hot-plug ESD and ignition noise. IC Role / Device Role / Timing Role: Primary clamping element on 5V/12V auxiliary rails feeding audio amplifiers and touch controllers. Use Value: Withstands ±30kV ISO10605 contact discharge and clamps within 1ns to preserve signal integrity of high-speed video links. |
| ADAS Camera Module | Electric Power Steering (EPS) |
Use Scenario: Protection of FPD-Link III serializer power pins against cable discharge events and harness-induced transients in rear-view cameras. IC Role / Device Role / Timing Role: Local TVS mounted adjacent to serializer IC power entry point to minimize inductance in clamping path. Use Value: Low clamping ratio (24.4V/15V = 1.63) ensures serializer supply remains within absolute maximum rating during 10/1000μs surges. | Use Scenario: Input protection for EPS motor driver gate drivers and MCU power domains subjected to high-current switching noise and battery reversal. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS used in conjunction with reverse-polarity MOSFET to handle both positive and negative transients. Use Value: 200A IFSM rating supports repeated exposure to ISO7637-2 Pulse 2a (+50V) during motor commutation without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC15-13-F | Same SMC package, lower 600W PPK, 27V VC @ 33A IPP | Not suitable for ISO7637-2 Pulse 1 (–100V); limited to lower-energy infotainment rails | Select only if system surge energy is confirmed ≤600W and clamping voltage margin allows 27V |
| SMCJ15A-Q | Identical electrical specs but non-tape-and-reel packaging (bulk/tray), no -13-F suffix | No difference in circuit performance; unsuitable for automated SMT lines requiring 3000-piece reels | Choose only for manual prototyping or low-volume hand-soldered builds |
Compared with SAC15-13-F and SMCJ15A-Q, SMCJ15AQ-13-F uniquely delivers 1500W surge handling in tape-and-reel format with full AEC-Q101 documentation, making it the sole choice for high-reliability, high-volume automotive power rail protection requiring PPAP submission.

FAQ
What is the clamping voltage of SMCJ15AQ-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 24.4V measured at 61.5A peak pulse current using the standard 10/1000μs waveform. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and reflects worst-case performance under surge conditions defined in ISO7637-2.
Is SMCJ15AQ-13-F bidirectional or unidirectional?
SMCJ15AQ-13-F is unidirectional, indicated by the absence of the "C" suffix (which denotes bidirectional versions like SMCJ15CAQ-13-F). It features a cathode band marking and is intended for DC power line protection where polarity is fixed, such as 12V battery feeds.
Does SMCJ15AQ-13-F meet AEC-Q101 requirements for automotive use?
Yes - SMCJ15AQ-13-F is fully AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Qualification includes HTOL, temperature cycling, ESD-HBM (≥8kV), and mechanical shock testing per AEC-Q101 Rev D.
What is the thermal resistance junction-to-lead (RθJL) for SMCJ15AQ-13-F in SMC package?
RθJL is not explicitly published in DS40741 Rev. 8–2, but the datasheet specifies steady-state power dissipation PM(AV) = 5.0W at TL = +75°C. Using the standard SMC thermal model and typical PCB copper area (≥1 sq-in), RθJL is approximately 15°C/W - sufficient to maintain TJ ≤150°C under 5W continuous dissipation with proper layout.
